Description

Technical Field

[0001] The utility model belongs to the technical field of prestressed concrete pipe pile construction, and particularly relates to a vibration control device for prestressed concrete pipe pile construction. Background Art

[0002] With the rapid development of urban construction and infrastructure construction, prestressed concrete pipe piles, as a common form of pile foundation, have been widely used because of their advantages such as relatively low engineering cost, reliable quality, easy length adjustment and fast construction speed.

[0003] However, during the construction of prestressed concrete piles, vibrations are unavoidable due to the use of construction methods such as hammering. If these vibrations are not effectively controlled, they can not only damage the ground around the construction site but can also spread to adjacent buildings, posing a potential threat to their structural safety and functionality.

[0004] Currently, traditional vibration reduction methods, such as installing vibration isolation trenches and walls, are commonly used to control vibration during the construction of prestressed concrete pipe piles. However, these methods suffer from long construction periods, high costs, and limited vibration reduction effects in practical applications.

[0005] To this end, we proposed a vibration control device for prestressed concrete pipe pile construction, which can effectively reduce and control the impact of vibration generated during pipe pile construction on the ground, and reduce the vibration effect from spreading to neighboring buildings and affecting the safety of neighboring buildings. Utility Model Content

[0006] The purpose of this invention is to provide a vibration control device for prestressed concrete pipe pile construction, which can effectively reduce and control the impact of vibration generated during pipe pile construction on the ground, reduce the vibration effect from spreading to adjacent buildings, and affect the safety of adjacent buildings.

[0007] The technical solutions adopted in this application are as follows:

[0008] A vibration control device for prestressed concrete pipe pile construction, comprising a ground and a pipe pile body, wherein a placement groove is excavated on the ground, and a vibration control component is arranged inside the placement groove;

[0009] The vibration control component includes a reinforcement layer, a dielectric layer and a buffer layer arranged inside the placement groove, a plurality of through grooves are opened on the buffer layer, a fixed shaft is provided inside each of the through grooves, two sliders and a spring are sleeved on the fixed shaft, the spring is provided between the two sliders, and a movable plate is hingedly provided on the two sliders, and the end of the movable plate away from the slider is hingedly connected to a contact plate that fits with the inner wall of the placement groove, and an L-shaped bracket is provided on the top of the contact plate, and an arc plate is installed at one end of the L-shaped bracket, and the arc plate fits with the pipe pile body.

[0010] Furthermore, fixing teeth are provided at the bottom of the reinforcement layer, the dielectric layer and the buffer layer.

[0011] Furthermore, an anti-slip layer is provided on the contact plate.

[0012] Furthermore, a smooth layer is provided on the curved plate.

[0013] Furthermore, the through slot matches the slider.

[0014] Furthermore, a rubber layer is provided on the inner wall of the buffer layer.

[0015] The technical effects achieved by this utility model are:

[0016] Before construction, the ground is excavated to form a placement groove, and the vibration control assembly is then placed within the placement groove. When the pile body is hammered, the vibration force generated by the pile body is transmitted to the curved plate and the ground. These vibration forces act on the contact plate, which drives the movable plate to move, which in turn drives the slider to squeeze the spring. The slider can move relative to the spring, thereby further absorbing and dispersing the vibration energy, thereby reducing the vibration force on the ground. The corresponding force then acts on the dielectric layer, which absorbs and disperses the vibration energy from the pile, reducing the vibration intensity. The reinforcement layer strengthens the structure and ensures that it will not deform or damage during vibration. This device can effectively reduce and control the impact of vibration generated during pile construction on the ground, reducing the vibration effect from propagating to adjacent buildings and affecting their safety.

[0023] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0024] like Figure 1-4 As shown, the technical solution adopted by the present invention is as follows: a vibration control device for prestressed concrete pipe pile construction, comprising a ground 1 and a pipe pile body 2, a placement groove 3 is excavated on the ground 1, and a vibration control component is arranged inside the placement groove 3;

[0025] The vibration control component includes a reinforcement layer 4, a dielectric layer 5 and a buffer layer 6 arranged inside the placement groove 3. A plurality of through grooves 7 are opened on the buffer layer 6. A fixed shaft 8 is provided inside each through groove 7. Two sliders 9 and a spring 10 are sleeved on the fixed shaft 8. A spring 10 is provided between the two sliders 9, and a movable plate 11 is hingedly provided on the two sliders 9. The end of the movable plate 11 away from the slider 9 is hingedly provided with a contact plate 12 that fits with the inner wall of the placement groove 3, and an L-shaped bracket 13 is provided on the top of the contact plate 12. An arc plate 14 is installed at one end of the L-shaped bracket 13, and the arc plate 14 fits with the pipe pile body 2.

[0026] Its working principle is as follows: before construction, the ground 1 is excavated to form a placement groove 3, and then the vibration control assembly is placed inside the placement groove 3. When the pipe pile body 2 is hammered, the vibration force generated by the pipe pile body 2 is transmitted to the curved plate 14 and the ground 1. These vibration forces act on the contact plate 12, which drives the movable plate 11 to move. The movable plate 11 drives the slider 9 to squeeze the spring 10. The slider 9 can move relative to the spring 10, thereby further absorbing and dispersing the vibration energy, thereby reducing the vibration force on the ground 1. The corresponding force then acts on the dielectric layer 5, which absorbs and disperses the vibration energy from the pipe pile, reducing the vibration intensity. The reinforcing layer 4 plays a role in strengthening the structural strength, ensuring that no deformation or damage occurs during the vibration process. This device can effectively reduce and control the impact of vibration generated during pipe pile construction on the ground 1, reducing the vibration effect from propagating to adjacent buildings and affecting the safety of adjacent buildings.

[0027] Before excavation begins, a geological survey of the excavation area is required. Leveling the site and clearing away obstacles and debris will facilitate excavation. Appropriate excavation equipment should be selected based on the actual ground conditions and construction requirements. For example, for harder rock layers, an excavator combined with a breaker may be used; for softer soil layers, an excavator can be used directly. During the excavation process, strict adherence to safety procedures is essential to ensure the safety of construction personnel. For example, warning signs should be posted, hard hats should be worn, and the excavation equipment should be kept stable.

[0028] At the same time, the reinforcement layer 4 is made of a material with a certain strength, such as steel. This arrangement enhances the structural strength and ensures that no deformation or damage occurs during the vibration process.

[0029] The dielectric layer 5 is located on one side of the reinforcing layer 4 and is made of a material with shock-absorbing properties (such as rubber, foam, etc.). When vibration occurs, the dielectric layer 5 can effectively absorb and disperse vibration energy and reduce vibration intensity.

[0030] The bottom of the reinforcing layer 4 , the dielectric layer 5 and the buffer layer 6 are provided with fixing teeth, which can fix the entire device inside the placement groove 3 to prevent tilting.

[0031] The contact plate 12 is provided with an anti-skid layer, and since the contact plate 12 contacts the inner wall of the placement groove 3 , an anti-skid effect can be achieved.

[0032] A smooth layer is provided on the arc-shaped plate 14. Since the pipe pile body 2 moves downward, the smooth surface can reduce friction and prevent the device from being damaged.

[0033] The through slot 7 is matched with the slider 9 , and what is matched here is that the slider 9 can move smoothly inside the through slot 7 without getting stuck.

[0034] A rubber layer is provided on the inner wall of the buffer layer 6, and the rubber layer can further achieve a shock-absorbing effect.

[0035] It should be noted that the height of the device of the present invention is the same as the height of the pipe pile body 2, which can effectively isolate vibration.

[0036] The working principle of this utility model is as follows: before construction, the ground 1 is excavated to form a placement groove 3, and then the vibration control component is placed inside the placement groove 3. When the pipe pile body 2 is hammered by the hammer method, the vibration force generated by the pipe pile body 2 is transmitted to the arc plate 14 and the ground 1. These vibration forces act on the contact plate 12, which drives the movable plate 11 to move. The movable plate 11 drives the slider 9 to squeeze the spring 10. The slider 9 can move relative to the spring 10, thereby further absorbing and dispersing the vibration energy, thereby reducing the vibration force on the ground 1. The corresponding force then acts on the dielectric layer 5, which absorbs and disperses the vibration energy from the pipe pile through the dielectric layer 5, reducing the vibration intensity. The reinforcing layer 4 plays a role in strengthening the structural strength, ensuring that deformation or damage will not occur during the vibration process. The device can effectively reduce and control the impact of the vibration generated during pipe pile construction on the ground 1, and reduce the vibration effect from propagating to adjacent buildings and affecting the safety of adjacent buildings.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
